. This invention relates to a device for oscillating the loaded beam roll o-f'ajig dyeing machine orsimilar machines handling wet rolls of textile fabric and to the method 01' using. same.

An object of the invention is to provide a device for and method of preventing'a roll of dyed or otherwise wetted cloth from becoming sideheavy, water logged, unevenly tensioned and otherwise injured. Other objects of the invention will appear from the following detailed description and drawing.

' In the drawing:

Fig. '1 is an end elevation of a jig dyeing device showing a method of attaching an oscillating device thereto;

. Fig. 2 is a side elevation of a jig dyeing device showing the method of mounting the oscillating device thereon.

The invention is herein described with reference to jig dyeing machines.

' plicable, to washing machines, coating machines,

sizing machines or other like machinesthat furnish a liquid treatment to atextilefabric that is wound into a roll prior to final drying.v

In the processing of textile fabrics wherein the textile fabrics are wound upon a horizontal beam into a roll while they are still wet from a processing treatment, if the roll remains stationary the liquid of the roll tends to drain to the bottom of the roll. Thus, after but a few minutes standing the difference of density of the top and bottom of the roll is easily seen, the top of the roll appearing clamp to dry while the bottom ofrthe roll is flooded with liquid. Most types, of yarns have a varying tensile strength and elasticity, according to the amount of moisture present, whereby there is imparted to rolls of fabric water-logged on one side and drying on the other side corresponding strips of varying stresses and filament elongation. If the liquid present is dye bath liquor the fabric situated in the water-logged part of the roll is dyed a deeper shade than the fabric in that part of the roll that is immediately drained. r

I have found that if the roll of material is continually oscillated while containing a liquid, the liquid will remain evenly distributed throughout the roll. This principle especially lends itself to dyeing by meansof a jig. In jig dyeing, a fabric is given a certain number of runs through a dye bath and is wound upon a roll; the attendant then takes a sample of the fabric, washes and dries it, and compares it with a guide for color; if the color is too light it is again run th ou h e bath and a n. sa p ed unt t It is, however, ap-.

desired color is reached. While these samples are being taken and processed, the fabric remains on the roll above the. dye bath, and if the roll is not oscillated the dye bath liquid drains to the lower part of the roll, causing a '5 deeper dyeing and greater stretching of the fabric in that part of the roll.

According to my invention I construct a device that is adapted to prevent injury to wetted fabric while standing on a roll. adapted to prevent injury to the fabric by oscillating the roll through a sufiicient arc to. maintain any liquid therein in an evenly distributed condition. The device is so constructed that it maybe contacted with either one of a number of roll beams or it may be disconnected from all the roll beams to a neutral position.

This invention is not limited to application to a jig dyeing machine but'may be applied to any machine handling rolls of wetted fabric. The 20 invention, furthermore, is not limited to the type of jig dyeing machine shown in the drawing but may be adapted to operate on jig dyeing machines of any type of drive, any style of tank or tub or type or style of frame and supporting members. j Q Q In the drawing like numbers refer to like parts in both figures.

Suitable frame members H having legs I 2 for the support thereof and uprights [3 for supporting rolls, beams and driving mechanism, support a tank or vat I4 that may be of stone, porcelain, wood or metal depending upon the material it is to contain. The vat or tank is held in the frame by means of tie rods l5 on either side at the top and bottom. The uprights l3 have mounted therein suitable bearingslli and I1 for supporting shafts l8 and is that have mounted thereon beams 2| about which the fabric may be wound.

On one end of each of the shafts l8 and I9 are drums 22 that may act as driving connections or as brake drums for the beams 2!. On the other end at 23 of each of the shafts I8 and 19 may be driving means and clutches, etc., for turning the shafts in either direction or permitting the same to idle.

The dye jigs may be driven as single units or a seriesof thernmay be suitably placed side by side and driven by a single shaft running past their ends. The driving device that drives the beams for the purpose of drawing the fabric from a beamon one side of the machine through the bath in, the vat and winding same up on a beam on t e Ot r S de O he ma ine, not be g a 5.5.

The devicev is 10 part of this invention, has not been shown. Any of the driving means of commercial type dye jigs and washers may be employed.

Running past the end of the dye jig is a shaft 24 that may be of any suitable length, depending upon the number of machines it is desired to drive thereby. This shaft has mounted thereon a gear 26 driven by a worm gear 21 mounted in.- suitable bearings 28. This worm gear is driven from a suitable source of power 29 such as a driven shaft, electric motor, etc., by means of the pulleys 3| and 32 and the belt 33.

The shaft 24 has keyed thereto bevel gears 34 spaced along the shaft, adapted to register with driving means for an oscillator, at each dye jig, washer or similar device. Each gear 34 is adapted to drive a corresponding bevel gear 35 mounted for rotation upon a shaft 36. The gear 35 has mounted on the back thereof a female clutch member 3'! positively connected thereto or integral therewith. Slidably mounted upon the shaft 36 but-keyed against rotation thereon is a male clutch member 38 adapted to slide into and out of engagement with clutch member 31. The shaft 36 is suitably supported in bearings 39 on each end of the jig. The bearing 39 may be sup-' rod 43 the clutch members 38 and 31 are adapted to intermesh, thus connecting or disconnecting the positive driving means from the shaft 36.

Swiveled about the shaft 36 is a strap member 46 bent in a U-shape at the bottom. One stem of the U is adapted to loosely fit on the shaft 36, the other stem of the U being elongated to rise to an elevation above the dye jig or washer. The long arm of member 46 has mounted thereon a stub shaft 41 rotatably supporting a gear 48 so positioned as to meslr with gears 49 and M on the ends of shafts l8 and I9 respectively. On the long stem of the member 46 is an ear 52 having pivoted thereto a hand piece 53. Pivoted to the hand piece 53 at 54 is a rod 56, the lower end of which is formed into a member 5l-adapted to slide in a guideway 58 and engage notches 59, 6! and 62in a member 63,-which is bent in an arc the center of which corresponds with the shaft 36. This member is attached to the frame I I by the upper tie rods 15.

Mounted on the gear 48 at a suitable distance from the center thereof is a stub shaft 64 about which is rotatably mounted a bearing forming one end of a pitman rod 66. The opposite end of the pitman rod 66 is journaled on a stub shaft 61 mounted on a crank arm 68 attached in driving relation to shaft 36.

In operation, the fabric is unwound from the one beam, say I9, carried down and up through the bath in tank l4 and is wound upon the beam on the opposite side, say on beam I8. The material is then carried in a reverse direction back through the bath and onto the first beam and this is repeated any number of times. During this period of passing the fabric through the bath, the member 46 is held in a vertical position or an inoperative position by or at the notch 6| and the clutch 31, 38 is disengaged by pulling rod 43 away from the frame to an inoperative position of the clutchmember. when the fabric is wound upon either beam and it is desired to leave same there forany length oftime prior to re-running the same through the bath or removing same from the device, the arm 46 is rotated toward the loaded beam until the gears 4849 or 48-5|, depending upon which beam holds the material, are in driving relation and 5 the arm is held in such a position by means of the member 51 and either notch 59 or 62. The member 43 is then moved toward the machine, thus connecting the shaft 36 with the source of power. As the shaft 36 rotates, it rotates the crank arm 68, the radius of which is shorter than the distance of the stub shaft 64 from the center of the gear 48, thus creating through the pitman arm 66 an oscillation of the gear 48. The ratio of the distances, from center to stub shafts of 15 the gear 48 and crank 68, will govern the are through which the gear 48 will be oscillated. It is preferable to oscillate the gear 48 through more than 180 but less than 300. By varying the ratio between the gear 48 and the gears 49 and 20 51 the beam carrying the fabric may be caused to oscillate through an arc of any number of degrees from part of a revolution to several complete revolutions in each direction. It is preferable, however, to oscillate the roll through an are just slightly greater than 360.

Attached to each end of the fabric and to the respective beams [Band [9 is a guide strip that. carries the fabric'through the bath and about the various guide means submerged therein. If the oscillation arc of the loaded beam is great, then this guide strip must necessarily be of great length, thus it is preferable to maintain said are at approximately 360 C. I

The device herein described is useful for the 35 dyeing; washing or otherwise treating of fabrics of all kinds and is particularly useful in the treatment of fabrics containing filaments of cellulose acetate or other organic derivatives of cellulose.
